Applicable FCC Rules

- CFR 47 Part 15.247 2. Operational Condition The module is limited to OEM installation ONLY. The OEM integrator is responsible for ensuring that the end-user has no manual instruction to removeor install module. 3. Limited Module Procedure BTR-B89071SMA is limited Module. The module doesn't have its own power supply regulation. Therefore, the host product manufacturer must design the host product so that a constant voltage of 3.3V is applied to the module. 4. Trace antenna desings : N/A 5. RF Exposure consideration (CFR 47 Part 1, 1.1307(b), 1.1310) This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum 20 cm between the radiator and human body. 6. Antenna This modular has PCB pattern antenna. Any changes of antenna designs might require additional assessment. The Host antenna type shall be same type and antenna gain shall be less or equal to 1.56 dBi. 7. Label and compliance information The end user manual shall include all required regulatory information/warningas shown in this manual. If the FCC identification number is not visible when the module isinstalled inside another device, then the outside of the device into which the module isinstalled must also display a label referring to the enclosed module. This exterior label can use wording such as the following:

Contains FCC ID : 2ADQJ-B89071 any similar wording that expresses the same meaning may be used. 8. Information on test modes and additional testing requirements This modular was tested in standalone configuration. Integration of this modular into ahost equipment would require additional testing. 9. Additional testing, Part 15 Subpart B disclaimer The grantee should include a statement that the modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. eSSys Co., Ltd Proprietary & Confidential BTR-B89071-SMA(B-ROM-VI) Bluetooth 5.0 Rom Module 10.

Cover Letter-Modular Approval FCC ID: 2ADQJ-B89071 Date: May 23, 2022 Gentlemen:

Theres an BTR-B89071SMA that would like to have your authorization as a modular approval. The specific product as below, BTR-B89071SMA with its designed features and specified description, meets special requirements for limited modular approval on FCC KDB996369 by cross-reference list below. Company Model Name Model Number FCC ID Requirement of FCC KDB996369 ESSYS CO.,LTD BTR-B89071SMA BTR-B89071SMA 2ADQJ-B89071 Comply (Y/N 1. The radio elements shall have the radio frequency circuitry shielded. Physical / discrete and tuning capacitors may be located external to the shield, but must be on the module assembly. Y The EUT provides the RF shielding. See EUT photo. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over- modulation. Y The EUT has its buffered modulation. Please see the Block Diagram in Manual. 3. The modular transmitter must have its own power supply regulation. 4. The modular transmitter must comply with the antenna and transmission system requirements of Sections 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler

(at all connections between the module and the antenna, including the cable). The professional installation provision of Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. N The EUT doesnt have its own power supply regulation. The host product manufacturer must design the host product so that a constant voltage of DC 3.3V is applied to the module. N Professional Installation Only Equipment. Specific guidance will be provided to host manufacturer and same type (PCB) and less gain antenna shall be used for this module. No external power amplifier can be connected to this module. 5. The modular transmitter must be tested in a alone configuration, i.e., the module must stand not be inside another device during testing. Y The EUT was tested with a test board, Please see test report and setup photo Y Please see exhibition label sample for the FCC ID of this module. And also in the exhibition Users manual, there are instructions give to the OEM on how to label the end product. 6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:

Contains Transmitter Module FCC ID : 2ADQJ-

B89071 or Contains FCC ID : 2ADQJ-B89071 Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. Y The EUT is compliant with all applicable FCC rules. Details instructions for maintaining compliance are give in the User Manual. Y The EUT complies with RF exposure requirement. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Thank you. Sincerely, By:
